TO ALL WHOM 1T MAY CONCERN:

Beit known that I, JOHN BUEGG, of St. Louis, in the county of St. Louis,and State cf Missouri, have made certain 4new and useful Improvements inBungs for Barrels; and I'do hereby declare 4that the following is a.full and cleardescription. thereof, reference being had to theaccompanying drawings, and to the letters of reference markedrthcreon.

The objectvof this'invention is to produce a bung and bushing for beerand other barrels that will he capable of enduringtherongh usage thatbungs are usually subjected to by being continually inserted and4withdrawn from barrels. I am well aware that iron bushings-have beforebeen used -for barrel-brings, but` they have always been attached to thebarrel by means of rivets alone, and consequently have readily becomeloosened. Into these metallic bushings wooden plugs have been driven,and these have, as a matter of course, caused the barrel to be poundedwith a heavy instrument, for the purposeof the withdrawal of thebung,and this pounding has, as it'inevitably must, caused* the rapiddestruction of that stave of the cask in which it was placed. Then thebung was so securely driven in that much time and labor were requiredtowithdraw it, and it was consequently difficult vand tedious towithdraw the bung slightly for thepurpose of giving ventito the cask. Toremedy these. evils, and more especially the last, is the object ofthepresent invention. In this case a metallic bushing is used, whichis tobe beth screwed into the staveand riveted to it. Then' the bung isscrewed into the bShiPg, and 2. Cap-plate screwed down-.otter it. soasto thoroughly` protect it during transportation. An airchannel iscut'in 'one side of the bung, for the purpose of admitting air totheinterior of the cask for vent, when the bung is but slightlywithdrawn.

To enable thoserskilled in the art to make'and'use my improved bung, Iwill proceed to describe its construction andoperation. y v i .Figurelof the drawings is a plan of the improved-bung and bushing.

Figure 2 is a plan of the same, having the exterior cap removed. i' Y 1'Figure 3 is a sectional elevation. l i Figure 4 isa plan of the bungwithout the bushing. Figure 5 is a perspective view of anotherv form ofmy invention. l

` The Vbushing"consists of a neck-piece, A, and aflange, A. -Theneck-piece A. has both its interior and exterior surface provided withscrew-threads. The exterior threads a arci for the purpose of screwingthe bushing inte .the bung -stave, while the threads a, or the interiorthreads, are for the purpose ot' securing thel bung-into-the bushing. Inaddition to the threads a, as a means of securing the bushing to thestave, the flange A is provided with a-series of holes, a2, throughwhich rivets are to be inserted and 'secured to the stnvcl- The bung Bis a cylindrical stopper, with screw-threads on its periphery adapted totit the screw-threads al of the bushing. The top end of the bung isrecessed, so as to form a central square shank, b, adapted to theapplica- 'tion of awrench for the'purpose of screwing the bung into thebushing. On one side ofthe bung is a channel, b, as seen best in l'igf4.When the bung is screwed down tightly into the bushing its bottom lendwill form a tight joint on thepacking a?, which rests uponau annularscat formedv on the interior of the bushing, but when the bung isslightly unscrewed a. sufficient amount Ot' external air will passthrough the channel b to afford vent for the barrel, and ,in thismannerjust enough 'and no more air may be 'admitted to afford therequired vent, and

the contents of the barre-l will in consequence remain sweet a longertime than if the air were allowed to enter? in larger volumes. `When thebung is screwed clown tightly into its bushing a. cap-plate, C, is to beplaced ovcr it, and secured to the bushing-Harige by means of the screwsc.

Fig. 5 represents another form of my invention, in which the outersurface oF the bushing :is runde conical,`

the taper being downward, so that the bushingr may be screwed moretightly'into the stave.

Having described my invention, whatmI claim is- 1.. The bushing A A',when provided with screw-threads a a and rivet-holes a?, and with a. capor lockplate, C, as described and for the purpose set forth.

2. I claim the bung B, when provided with screw-threads, by means ofwhich to secure it to the bushing,

" "zndvthe vent-channel b1, and wrench-shank b, as and for the purposeshown and described.

ln testimony of which invention I hereunto set my hand in presence of-.-
